My job is to control a multimeter (Agilent 3458A) with an Agilent 82357A GPIB controller. The 82357A is connected to a PC with Windows 7 & LabVIEW 2011 installed.
1) After Keysight IO Library installed, 82357A can be found in Windows Device Manager.
2) I can communicate (sending commands or query) with the multimeter in NI VISA Interactive Control.
When I program the multimeter in LabVIEW with VISA, VISA write (sending command) is fine, but VISA read failed (the return string was empty and 0xBFFF0015 error occurred).
Any suggestion?
